Re: Installing weka on ubuntu

You seem to be remotely connected without a graphical environment. In such a case you can't use Weka's user interface.

Instead, use classifiers etc directly, eg for J48:

java -cp weka.jar weka.classifiers.trees.J48 -h

-h to display the command line help.

Cheers, Peter
